ZooMAb® antibodies represent an entirely new generation of recombinant monoclonal antibodies.

Each ZooMAb® antibody is manufactured using our proprietary recombinant expression system, purified to homogeneity, and precisely dispensed to produce robust and highly reproducible lot-to-lot consistency. Only top-performing clones are released for use by researchers. Each antibody is validated for high specificity and affinity across multiple applications, including its most commonly used application. ZooMAb® antibodies are reliably available and ready to ship when you need them.


Clone 3L17 is a ZooMAb® Rabbit recombinant monoclonal antibody that specifically detects Ras-related protein Rab5A. It targets an epitope within 16 amino acids from the C-terminal region.


KLH-conjugated linear peptide corresponding to 16 amino acids from the C-terminal region of human Ras-related protein Rab5A.

Target description

Ras-related protein Rab-5A (UniProt: P20+D9339; also known as EC:, Rab5A) is encoded by the RAB5A (also known as RAB5) gene (Gene ID: 5868) in human. Rab5A is a member of the small GTPase superfamily that is localized in the cytosolic side of plasma membrane and endosomes. It plays important roles in cellular differentiation, neurogenesis, exocytosis, and protein transport. It is a rate-limiting catalyst of the endocytic uptake and delivery to early endosomes of both fluid-phase and receptor-mediated endocytic tracers, as well as of homotypic endosomal fusion. It is required for endosome fusion with the plasma membrane. It localizes to early endosomes where it is involved in the recruitment of RAB7A and the maturation of these compartments to late endosomes. It drives the maturation of endosomes by transporting vacuolar (H+)-ATPases from trans-Golgi network to endocytic vesicles. Rab5A cycles between active GTP-bound and inactive GDP-bound states. In its active state, it binds to a variety of effector proteins to regulate cellular responses such as of intracellular membrane trafficking and from the formation of transport vesicles and their fusion with membranes. Active GTP-bound form recruits different sets of downstream effectors to membrane that are directly responsible for vesicle formation, movement, tethering, and fusion. This ZooMAb® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.

Physical form

Purified recombinant rabbit monoclonal antibody IgG, lyophilized in PBS with 5% Trehalose, normal appearance a coarse or translucent resin. The PBS/trehalose components in the ZooMAb formulation can have the appearance of a semi-solid (bead like gel) after lyophilization. This is a normal phenomenon. Please follow the recommended reconstitution procedure in the data sheet to dissolve the semi-solid, bead-like, gel-appearing material. The resulting antibody solution is completely stable and functional as proven by full functional testing. Contains no biocide or preservatives, such as azide, or any animal by-products. Larger pack sizes provided as multiples of 25 μL.


300 μg/mL after reconstitution at 25 μL per vial. Please refer to guidance on suggested starting dilutions and/or titers per application and sample type.

Storage and Stability

Recommend storage of lyophilized product at 2-8°C; Before reconstitution, micro-centrifuge vials briefly to spin down material to bottom of the vial; Reconstitute each vial by adding 25 μL of filtered lab grade water or PBS; Reconstituted antibodies can be stored at 2-8°C, or -20°C for long term storage. Avoid repeated freeze-thaws.
